ALMA FACTS III. High-Resolution CO(2-1)/CO(1-0) Maps of Twelve Nearby Galaxies
Amanda M Lee, Jin Koda, Fumi Egusa +4
We present early results from a high-resolution analysis (100-200pc) of the CO(2-1)/CO(1-0) line ratio in twelve nearby galaxies. We use new ALMA CO(1-0) observations from th…
ALMA FACTS. II. Large Scale Variations in the 12CO(J=2-1) to 12CO(J=1-0) Line Ratio in Nearby Galaxies
Shinya Komugi, Tsuyoshi Sawada, Jin Koda +4
We present 12CO(J=1-0) mapping observations over ~1/2 of the optical disk of 12 nearby galaxies from the Fundamental CO 1-0 Transition Survey of nearby galaxies (FACTS), using the…
Dynamically-Driven Evolution of Molecular Gas in M83 Traced by CO 2-1/1-0 Line Ratio Variations
Jin Koda, Fumi Egusa, Akihiko Hirota +3
We show the variations of the CO J=2-1/1-0 line ratio (R21) across the barred spiral galaxy M83, using the 46 pc resolution data from ALMA. The R21 map clearly evidences the system…
Whole-disk sampling of molecular clouds in M83
Akihiko Hirota, Jin Koda, Fumi Egusa +17
We present a catalog of clouds identified from the CO (1--0) data of M83, which was observed using Atacama Large Millimeter/submillimeter Array (ALMA) with a spatial resolut…
Sub-Parsec-Scale Jet-Driven Water Maser with Possible Gravitational Acceleration in the Radio Galaxy NGC 1052
Seiji Kameno, Yuichi Harikane, Satoko Sawada-Satoh +5
We report sub-pc-scale observations of the 321-GHz HO emission line in the radio galaxy NGC 1052. The HO line emitter size is constrained in milliarcsec distributed…
